IMPROVEMENT IN HOSE-GOUILING WRENHI @tige ,rlgthnle mmh tu in tipa tttrts rteutfuth mating peut at tigt state.

TO ALL 4WHOM IT MAY OONCERN:

Be it known that I, ALBERI` F. ALLEN, of the city and county of Providence, and State of Rhode Island, have invented a new and improved Signal Hose-Wrench forCoupling and Uncoupling Engine-Hose; and I do hereby declare that the following is a full, clear, and 'exactdescription ofthe same, reference being had to the accompanying drawings, making partei' this specification, in whichi Figure 1 is a view of my improvedhose-wrench applied to a hose-couplng in the way of its use.

Figure 2 is another view edgewise, longitudinally, ofthe same.

Similar letters indicate like parts inl all the figures.

The invention herein described is designed more especially to operate and carryinto full effect the'principle of action and the purposes of the improved hose-coupling patented by me, September 3, 1867, for stopping the How of water towards the nozzle or discharging-point, and of starting the flow of water again instantly, at will.

In addition to the purposes and uses of said coupling set forth inthe specification attached to the said patent of September 3, .1867, I have discovered by practice that the stream or body of water'that passes from the engine or pump to the nozzle from which it is discharged, may be employed as a means of communicating orders or directiousfr'om the engineer who has charge of the engine or like apparatus, to those having charge of the hose-pipe at the other end of the line of hose connectedwith such engine, or az'ce versa, by quickly or instantly stopping or starting the iiow of water, once, twice, or thrice, or any given number of times, such stopping and starting ofthe water being signals corresponding with those of the electric or magnetic current in telegraphing, and, when understood and agreed upon, will, in its way, subserve all the purposes of telegraphic communication between the engine and the hose-pipe or nozzle, and those having charge of either; and although the coupling, as described in the said specification, is fully complete and` perfect in itself to accomplish this desir able purpose, it is found that the ordinary hose-wrench, which partly spans and hooks upon one ofthe horns of the coupling, is entirelynnsuited to the .purpose of instantly turning the sleeve of said coupling in either direction, Ito stop and start the flow of water with that marked eilect as to answer thc purpose of. a signahfor the reason that the position of the ordinary hooked wrench has to be reversed at each stopping and starting produced by turning said sleeve, and that this reversing of the position and hold of the wrench cannot be done with that degree of promptness and precision to constitute an eifective signal. I have therefore invented a different construction of hose-wrench, by which the instant turning ofthe sleeve maybe accomplished, with out changingor removing it from its position, to'stop or start the flow of water in the manner and for the purposes contemplated,yand which is at the 'same time simple, and equally applicable and useful for the ordinary form of couplings for engine-hose, &c. v

My invention consists in so constructing the .hose-wrench with a socket to receive one of the horns or proe jcctions on the coupling, and with suitable horns or projections extending each Way from the said socket, so as to span the outside circumference of the coupling, that by means of a handle extending from said socket, the coupling or the sleeve of the coupling may be instantly turned in either direction-without removing or changing the position ofthe wrench.

In the drawings, G is the coupling, having/horns D D, as shown, andF is the socket of the wrench, which receivesone of the horns of said coupling, as shown in dotted lines. I-I is the'handle, in line with the centre-of the socket F, and B B are the horns of the wrench, projecting upon each side of the socket, and spanning one halt` ofthe circumference of the coupling. Thus constructed, it will be seen that the said wrench is a lever, of which either ofthe horns BEpaceordmg to the direction in which the coupling or its .sleeve iste be turned,)V is the fulcrum, the socket is 4the point of resistance, and the handle H is the point where the power-is applied to overcome such resistance, and that the eifeet and force is exertedoequally in turning in either direction without removing the wrench from the coupling, and therefore the sleeve of my imp'ioved patented coupling may be instantlyxturued, first in one direction and then in the other, topopen and close the passages at whichl the Water From the hose escapes, and with suc definite signalyto those in charge at either end.

hose,tai1d to serve all purposes of e What I claim, and desire to secure by Letters Patent, is- The Signal-hose wrench, constructed suhstantiaillgv as herein described, with n. socket, D, the spanning-horns B, `and. handle H, for the purposes4 set forth.

ALBERT F. ALLEN.
